ELECTRIC LAMP AND HOLDER THEREFOR.

SPECIFICATION forming part of Letters Patent No. 277,645, dated'May 15, 1883.

Application filed January 19, 18815. (No model.)

To all whom it may concern: nearly parallel as practicable. Their ends are Be it known that I, EDWARD WESTON, a then connected by across-piece,]), of some insubject of the Queen of Great Britain, and a sulating material. This may be asimplepiece resident of Newark, in the county of Essex of wood or similar substance,with holes drilled and State of New Jersey, have invented cerin it for the passage of the wires, or split and tain new and useful Improvements in Incanclamped onto the wires by a screw. I prefer, descent Lamps and Holders for the Same, of however, to use for this purpose a small mass which the following is a specification. of glass, which may be either wound on,

This invention relates to improvements in molded, or otherwise applied to the wires. to the construction of incandescentlamps, and in When glass is used the ends of the wires may the sockets or holders designed for use therebe slightly bent, as shown in Fig. .1.- with, the object of the improvements being With a lamp thus constructed I employ a mainly to simplify the construction of the socket o'r holder containing movable plates, means for retaining the lamps in position and clamps, or their equivalents, that retain the is completing the circuit through the same. For lamp inposition by engaging or looking with this purpose I employ a lamp of the ordinary the cross-piece D, the most convenient form of form, inwhich the conductors are sealed into this holder of which I am aware being that the glass of the globe, and extend from the illustrated in the drawings. bottom of the neck.

It is to be observed that the invention is not restricted to the specific construction of the holder above described, but includes any other combination of parts that operates in substantially the same way to lock the lamp in the socket, by locking, grasping, or engaging with the cross-piece D.

The socket is to be used in the usual way, in conjunction with a bracket-arm or similar support, and may be varied in design to conform to lamps of other shapes than that shown.

I would state that features herein shown or described, but not specifically claimed, will be made the subject of other applications.

What I now desire to secure by LettersPatcut is- 1. The combination, with the supportingconductors of an incandescent lamp, of an insulating cross-piece fixed on the conductors outside the globe, substantially as and for the purpose set forth.

2. The combination, with an incandescent lamp having an insulating cross-piece secured to the conductors outside and at a short distance from the globe, of a socket or holder and clamping or looking devices contained therein, for retaining the lamp in position by locking, grasping, or engaging with the crosspiece in substantially the manner set forth.

3. The combination, with an incandescent lamp having an insulating cross-piece secured to the conductors outside and at a short distance from the globe, of a socket or holder, and clamping or locking devices forming the terminals of an electric circuit and contained within the holder, the said locking devices being adapted to make contact with the conductors of the lamp, and to retain the lamp in position by locking, grasping, or engaging with the cross-piece in substantially the manner set forth. v

4. The combination, with an incandescent lamp having an insulating cross-piece secured to the conductors outside and at a short dis tance from the globe, of a socket or holder, and movable plates, jaws, or clamps contained therein, and adapted to close over the crosspiece, and therebylock the lamp in the holder, as described.

5. The combination, with an incandescent lamp having an insulated cross-piece secured to the conductors outside and at a short distance from the globe, of a socket or holder, spring slides or jaws contained therein, and insulated pins projecting from the holder for operating saidslides or jaws, whereby they may be opened for the. insertion of the insulating cross-piece and caused to close over the same and lock the lamp in the holder, as described.

6. The combination, with an incandescent lamp having a cross-piece of insulating material secured to its conductors outside and at a short distance from the globe, of a socket or holder, sliding plates orjaws capable of closing over the cross-piece and locking'the lamp in the holder, pins extending from the sliding plates or jaws for opening the same, and springs for forcing the same together over the cross-piece and into contact with the con-ductors, as and for the purpose set forth.

v7. The combination, with the conductors of an incandescent lamp, of a mass or bar of glass molded or otherwise fixed on the said conductors at a short distance from the globe, as and for the purpose set forth.

In testimony whereof I have hereunto set my hand this 12th day of January, 1883.
